THOMAS C. MORRIS, OF LITTLE ROCK, ARKANSAS.

CONVEYER-FLIGHT.

To all whom it may concern:

Be it known that I, THOMAS C. MORRIS, a citizen of the United States,residing at Little Rock, in the county of Pulaski and State of Arkansas,have invented certain new and useful Improvements in Conveyer-Flights,of which the following is a specification.

This invention relates to the class of conveyers, and more particularlyto the class in which the endless conveying element is provided with aplurality of carrying devices commonly called flights in the art.

The present invention contemplates an improvement in the flightelements, whereby they are cheap and easy to construct, easy ofapplication to the power element, and are strong and serviceable.

F or a full understanding of the invention, reference is to be had tothe following detail description and to the accompanying drawings, inwhich Figure 1 is a plan View of a. fragment of an endless power chainand indicating one of the flights in position, and Fig. 2 is atransverse section of the power chain on the line 22 of Fig. 1, showinga rear elevation of the flight.

Throughout the following detail description and on the several figuresof the draw ings, similar parts are referred to by like referencecharacters.

Referring particularly to the drawings the numeral 10 indicates afragment of an endless power chain composed of a series of links 11 ofwell known form. Each link comprises parallel side bars and circularends, the links being connected each to each in planes at right anglesto each other.

The improved flight is composed of two main elements, a cross bar 12 anda brace 13. The bar 12 may be of any convenient form, but in the main ispreferably flat but with its ends curved rearwardly and inwardly, theextreme ends 12 thereof lying parallel with the main body of the flightand spaced therefrom forming sockets as indicated in Fig. 1. Said bar 12may be of any conven ient length, depending upon the width of the troughor box through which the conveyer operates for the conveyance of anysuitable materials such as coal, saw-dust, ashes, and the like. Alsosaid member may be of any desired elevation or width depending upon theamount of material desired to be conveyed thereby. As indicated the bar12 is provided intermediate of its ends Specification of Letters Patent.

Application filed December 29, 1908.

Patented Aug. 30, 1910. Serial No. 469,793.

with circular seats 14 and 15 to embrace the lower and upper barsrespectively of the link in which the flight is secured. The seat 15 issubstantially semi-circular, and while the seat 14 is indicated as ofsubstantially the same form it may be deeper if desired in order tobring the lower edge of the bar 12 nearer to the bottom of the trough orbox.

-The brace member 13 is adapted to bear against the end of the followinglink of the power device and has its ends located within the curved endportions of the bar 12, the space between the extreme ends 12 and thebody of the bar 12 being made to substantially conform to the thicknessof the said brace member. Intermediate of its ends said brace 13 isdeflected or curved rearwardly from the plane of the bar 12 so as toconstitute in effect a truss, whereby the rigidity of the flight isenhanced. Furthermore, the arrangement of the members 12 and 13 is suchas to prevent any likelihood of one end of the bar 12 being distorted orturned backwardly with respect to the link to which it is connected.

The brace member 13 may be of any suit able width or height, butpreferably is slightly narrower than the bar 12 in order to facilitateassemblage of the parts. Corresponding to the seats 14 and 15 of the bar12, the brace 13 is provided with seats 16 and 17, to receive thecorresponding side bars of the link. The bar 12 is provided near itsends with holes 12, and the brace 13 is provided with correspondingholes 13 the pairs of holes being adapted to register when the membersare assembled. Any suitable fastening devices such as rivets 18 areemployed to secure the parts in proper position after being assembled toprevent separation thereof. In assembling the flight with relation tothe link, the bar 12 is first introduced between the side bars of thelink and turned at an angle. The brace member 13 is then introduced andturned at such an angle that the extreme ends 13 thereof may be slippedinto the spaces between the extreme ends 12 and the body of the bar 12.At such time the seats of the flight members will receive the oppositeside bars of the link. The fastening devices 18 will then be inserted ina permanent position. When assembled as thus described the flight mayhave a slight longitudinal movement within the link, bearing against thenext link when in use, but will be prevented from turning from the rightangular relation to the main line of the power chain.

The parts of the device may be made of any suitable size or dimensionsand of any desired materials.

Having thus described the invention, what is claimed as new is:

1. In combination with a power chain embodying open links having sidebars, of a flight comprising a cross bar located between the side barsof a link, a deflected brace member also located between the side barsof the same link, said members having seats to receive the link bars,and means to secure the ends of the flight members together each to eachin a rigid manner.

2. In combination with apower chain embodying open links having spacedside bars, of a flight comprising a bar extending transversely betweenthe side bars of a link and having upper and lower seats to embrace thesaid side bars, the ends of said bar being bent rearwardly to formsockets, a brace member extending transversely between the side bars ofthe same link and having its extreme ends seated in said sockets, andfastening devices securing the ends of the flight members rigidlytogether.

3. The hereindescribed conveyer flight, comprising a flat bar having itsextreme ends bent rearwardly and thence inwardly forming sockets, abrace member adjacent to the said bar and having its extreme ends seatedin said sockets, the intermediate portion of the brace member beingspaced from the body of the first member, and means rigidly securingsaid members together.

4. In a flight conveyer, the combination of a power chain having links,each of which has parallel side bars, a cross bar located between theside bars of a link and having seats to embrace the same, the ends ofthe bar being provided with holes and the extreme ends being bentrearwardly to form sockets, a brace member extending transverselybetween the side bars of the same link, the extreme ends of the bracemember being located in said sockets, the intermediate portion of thebrace member being spaced from the bar, and the ends of the brace memberbeing provided with holes to register with those of the bar, andfastening devices passed through said registering holes to secure theparts rigidly together.

5. A carrier attachment comprising the combination with the links of achain, of a bar extending transversely of the link and having recessesin its edges to receive the bars of the link and a brace member securedto the rear portion of the bar and extending through the link, saidbrace also having recesses to receive the link.

In testimony whereof I afiix my signature in presence of two witnesses.
